202 ZOOLOGICAL EESULTS OF THE EUWENZORI EXPEDITION. 



Part III.

Family L y c i D ^. 



Lycus (Acantholycus) modestus, sp. n. (Plate VI. figs. 2 & 3.) 



Black; the explanate sides of the prothorax and the whole of the elytra, with the 

 exception sometimes of a black spot around the scutellum and a narrow black border 

 to the suture, ochraceous ; the lateral margins of the 2nd to 6th segments of the 

 abdomen sometimes fulvous. In general form this species resembles L. latissimus 

 Linn., but the elytra are less strongly expanded laterally and their apices less broadly 

 truncate in the male ; the sutural margins of the elytra are almost quite straight from 

 the base to a little past the middle and then begin to curve or bend inwards, the one 

 elytron from that point onwards overlapping the other. The forceps of the male is 

 similar in form to that of L. latissimus ; and by means of this character, as well as by 

 the presence of a sharp outer angle or short tooth to the truncated apex of the elytra 

 in the male, the species may be distinguished from L. constrictus Fahr., to which also 

 it has a strong general resemblance. 



Length 6 20 mm. ; breadth at base of elytra 5, at middle II mm. 



Length ? 19-20 mm. ; breadth at middle of elytra 7|— 10 mm. 



Hab. Ruwenzori, 5300 ft. {G. F. Scott Elliot), Mubuku Valley, E. Ruwenzori, 

 6000-13,000 ft. 



Variation. — In one female example the elytra have an apical black area which is 

 widest at the suture, where it joins the black sutural band. 



Lycus yittatcs, sp. n. (Plate VI. fig. 1.) 



d . Black; pronotum yellow at the sides; elytra yellow, marked with three broad 

 longitudinal black bands — one common, sutural, the others along the middle of each 

 elytron, beginning a little behind the shoulders and joining the sutural band at the 

 apex. Elytra subovate, narrower at the base than the base of the prothorax, elevated 

 near the suture at a little past the middle of their length, dehiscent from just behind 

 this elevation and having the sutural margins somewhat sinuate ; rounded externally 

 at the apex, the sutural angles more or less obtuse ; interspace between the 

 third and fburtb costse slightly swollen near the base. Forceps tridentate near the 

 apex. 



$ . Elytra much narrower than in the male and nearly parallel-sided, the submedian 

 black band of each elytron narrow and short, extending along the third costa'for only 

 about one-third of the length of the elytron from the apex. Seventh ventral plate of
